2. Claims.

The present; invention relates to improvements: in watchmakers. tools;and has reference more. particularly to a watch movement holder.

Qneoi the important; objects of the. present. inventionis to. provide.a. watch movement holder that is. capable of accommodating: varioussizes and shape of watch movements and which hold the: same. securelyand; conveniently while under-- some inspection and repair.

A further object of our invention resides. in the provision of a. watchmovement holder that does; not require mechanical adjustment in order toaccommodate various sizes of watch movements. 7

A still. further object. is to. provide a watch movement holder thatwill securely engage and support the watch movement in such a mannerthat the parts of the watch movement will be readily and easilyaccessible for repair and replacement. without interfering, with theoperating parts of the holder.

Another object of importance: is to provide a watch movement holder thatincludes means; for positive; locking engagement with the lateral flangeof they watch movement thus preventing any slippage or casualdisengagement oi the watch movem nt wh n positioned on the. holder.

A still further object is to provide a watch movement holder thatconsists of relatively few parts, thus rendering the same inexpensive inits manufacture and readily and; easily operable.

Other objects and advantages of this invention will become apparent fromthe following description, when taken in connection with theaccompanying drawing.

In the drawing forming a part of this specification and wherein likereference characters designate corresponding parts throughout theseveral views:

Figure 1 is a side elevation of our watch movement holder, showing awatch movement engaged and supported thereon;

Figure 2 is a top plan view of the holder;

Figure 3 is a longitudinal sectional view taken approximately on theline 33 of Figure 2;

Figure 4 is a vertical sectional view taken on the line 4-4 of Figure 3,and

Figure 5 is a similar sectional view taken on the line 5-5 of Figure 3.

In the drawing, wherein for the purpose of illustration, is shown thepreferred embodiment of our invention, the numeral I designatesgenerally the improved watch movement holder. This holder comprises aflat metal base plate 2 having downwardly extending leg portions 3 and 4at its respective ends.

A pair of spaced longitudinally extending slots 5 and 6 are formed inthe base plate 2, as clearly illustrated in Figure 2 and the purposethereof will be Presently apparent.

.An elongated rod 1 is slidablr disposed through registering openings;provided therefior in the leg portions; 3- and t. An: actuating; knob 8is arranged: on the; forward end of the rod: 1;.

A block. 9' is. adiiustably secured on the slidable red I: by means: orthe set; screw it and: thisbloclc engages with the underside of. the.base.- plate 2: for movement. therealonsz.

.A coil. sprin I I; encircles: the intermediate por tion of. theslidable rod t and is interposed lee-- tween. the. rearleg, portions andthe: adiacent. face of the block. 9: for: ncrmal'lr'ur ingr the. rod andblock: forwardly- Suitable; washers; l2 and 13' are arranged. on the:rod for cooperation with the, re;- spective ends or the coil. spring andtherear le portion and block respectively.

Extending; upward-1p from the front. part. of the base plate 2. are thestationary pins t4 and t5i These pins may be attached-to the baseplatein any sui able manner and; in the instant case they are shown. as;being: riveted. to; the; base plate. although we do not desire to; belimited tn the; par ticularmanner in which. these pins; may be. secured.

These pins are, located: between;v the; forward ends oi the respectiveslots; in the base. plate: 2.11615 the forward end or the. latter and inalinement; with the respective.- slots, as: is clearly illustrated thedrawing- The upper ends or these: stationary pins. are reduced. and.undercut to; forms the. shoulders. l6.- and; the beaded studs l'to Asimilar pair of pins I8 and I9 are removably secured to the top of theblock 9 by suitable screw threaded shanks 20 and 2| that extenddownwardly from these last mentioned pins through the respective slots 5and 6 and threaded into suitable sockets provided therefor in the block9.

The pins l8 and I9 constitute slidable members that move across the topface of the base plate simultaneously with the movement of the slidablepush rod 1 and the block 9 carried thereby.

The pin I 8 travels across the slot 5 and the pin l 9 moves along theother slot 6. These movable pins IB and I9 cooperate with the stationarypins [4 and I5, respectively, in the manner to be presently described.

The upper ends of the movable pins are also reduced and undercut,similar to the upper ends of the stationary pins I 4 and IE to form theshoulders 22 and the beaded studs 23.

In use, the knob 8 is pushed rearwardly, causing the spring II to becompressed and simultaneously moving the pins I 8 and I9 away from thepins I 4 and I5, thus permitting a watch movement of any shape or sizeto be positioned between the coasting beaded studs carried by the fourpins, with the lateral flange a uniformly provided in the watch movementb resting on the shoulders I6 and 22 of the respective pins and thebeaded studs contacting the adjacent peripheral portions of the watchmovement.

When the watch movement has been properly positioned on the shoulders,pressure on the knob 8 is released, causing the spring I! to move therod, block and movable jaws in a forward direction, thus assuring thewatch movement being securely engaged and held between the pins of theholder.

With the watch movement supported on the holder, the same may be placedon a table or other support to permit the necessary repairs andreplacements made to the watch movement, and this without anyinterference with the operating parts of the holder.

To release the watch movement from the holder, it is only necessary topush rearwardly on the knob and instantly, the movable pins are movedaway from gripping engagement with the watch movement, therebypermitting the same to be readily and easily removed.

It will thus be seen from the foregoing description that we haveprovided a watch movement holder that is capable of accommodatingvarious sizes and shapes of Watch movements and due to its simplicitycan be readily and easily operated. Further, our device will beinexpensive, strong and durable and at all times positive and efficientin carrying out the purpose for which it has been designed.

While we have shown the preferred embodiment of our invention, it is tobe understood that various changes in the size, shape and arrangement ofparts may be resorted to without departing from the spirit of theinvention and the scope of the appended claims.

Having thus described our invention, what We claim is:

1. A watch movement holder comprising a base plate, leg portionsdepending from the end portions thereof, said base plate havinglongitudinal slots formed therein, a pair of stationary pins extendingupwardly from the base plate adjacent one end of the respective slots, apair of coacting movable pins operable through the respective slots inthe base plate, means on the upper ends of the pins for engaging andsupporting a watch movement, a slidable rod extending through said legportions, 9, block secured on said rod, said movable pins being mountedon -the block, and spring means associated with the rod and holder fornormally urging the movable pins toward the stationary pins.

2. A watch movement holder comprising a base plate, leg portionsdepending from the end portions thereof, said base plate havinglongitudinal slots formed therein, a pair of stationary pins extendingupwardly from the base plate adjacent one end of the respective slots, apair of coacting movable pins operable through the respective slots inthe base plate, reduced beaded studs formed on the upper ends of thepins for engaging and supporting a watch movement, a slidable rodextending through said leg portions, a handle on one end thereof, ablock adjustably secured on the rod and underlying the base plate, saidmovable pins being mounted on the block, and a coil spring encirclingthe rod and disposed between one leg portion and the block for normallyurging the movable pins toward the stationary pins.
